Thanks. Maybe it will tickle down did a way. We are starting to get the monthly wash drive thru systems that seem, for the price, to be sum watts good deal. But they don't offer any amities other then no scratch, spot free an towel your gal. But no gas,, yet. It will fall south I am sure, cause. Seems to be a very lucrative business. But a no scratch situation on a black car needs a cloud. Thanks for the info on the octane.
